    ISO 18629 PSL : A STANDARDISED LANGUAGE FOR SPECIFYING AND EXCHANGING PROCESS INFORMATION

    Process specification language (PSL) is a standardized format for specifying the steps involved in a process. PSL is widely used in manufacturing, engineering and other fields where process documentation is important. ISO 18629 is the most recent version of PSL and it includes several improvements over its predecessors. In this article, we will explore some of these improvements and discuss how they can help you when creating process specifications.

    ISO 18629-1:2004 Industrial automation systems and integration — Process specification language — Part 1: Overview and basic principles

    ISO 18629-1:2004 defines a process specification language (PSL) that can be used to specify industrial automation systems (IASs).

    The main purpose of ISO 18629-1 is to help automate the process control and integration of IASs. The language provides a means for specifying the required process conditions and performance parameters for a given application.

    ISO 18629-1 is based on the Basic Process Control Language (BPCL) standard. BPCL was developed in the 1970s and has been widely used in process industries.

    ISO 18629-1 is structured into four parts: overview, basic principles, data structures, and operations. Each part contains detailed descriptions of specific features of the PSL.

    Part 1 of ISO 18629-1 covers the overview and basic principles of the PSL. Part 2 deals with data structures and how they are used in the PSL. Part 3 discusses operations and how they are used to specify process conditions. Part 4 contains examples of PSL applications.

    ISO 18629-42:2006 Industrial automation systems and integration — Process specification language — Part 42: Definitional extension: Temporal and state extensions

    Process specification language (PSL) is a standardized language for specifying and exchanging process information. ISO 18629-42:2006 defines PSL as a machine-readable language that can be used to specify and exchange process information between industrial automation systems.

    PSL provides a means of describing the temporal and state aspects of processes. It also provides a means of communicating the dependencies between processes.

    ISO 18629-42:2006 defines four temporal extensions to PSL: start time, duration, repetition period, and restart point. Additionally, ISO 18629-42:2006 defines two state extensions to PSL: beginning state and end state.

    ISO 18629-42:2006 is an annex to ISO/IEC 14882:2004, which specifies the machine-readable terminology used in industrial automation systems.

    ISO 18629-11:2005 Industrial automation systems and integration — Process specification language — Part 11: PSL core

    ISO 18629-11:2005 defines a process specification language (PSL) that can be used to specify and exchange process information between different industrial automation systems. PSL is based on the Process Specification Language (PSL) core specification, which was developed by the International Organization for Standardization (ISO).

    PSL can be used to describe the following aspects of a manufacturing or processing operation:

    The PSL specification provides a concise, unambiguous, and machine-readable language for specifying industrial automation processes. It can be used to communicate process requirements between system designers, operators, and maintenance personnel.

    ISO 18629-11:2005 defines the syntax and semantics of the PSL language. The PSL standard also provides detailed descriptions of the rules for constructing valid PSL expressions.

    ISO 18629-13:2006 industrial automation systems and integration — Process specification language — Part 13: Duration and ordering theories

    Duration and ordering theories (TOTs) are a way of specifying the duration and order of activities in industrial automation systems. They can help to ensure that tasks are completed in the correct order, and that tasks don’t overlap.

    TOTs can be used in both computer-aided manufacturing (CAM) and process control systems. They can be used to specify the start and end times of activities, as well as the order in which they should be performed.

    There are several different types of TOTs, including time-based TOTs, event-based TOTs, and cycle-based TOTs. each has its own advantages and disadvantages.

    If you need to specify the duration or order of an activity in an industrial automation system, you should use a TOT. It will help to ensure that the system runs smoothly and that tasks are completed in the correct order.

    ISO 18629-43:2006 Industrial automation systems and integration — Process specification language — Part 43: Definitional extension: Activity ordering and duration extensions

    Activity ordering and duration extensions for processes are important for ensuring efficient and effective industrial automation systems. This ISO standard provides definitions, terms, and examples to help specify and exchange process information using a standardized language.

    This ISO standard defines the following terms:

    Activity : An act or sequence of acts that is intended to produce a result.

    : An act or sequence of acts that is intended to produce a result. Start time : The time at which an activity starts.

    : The time at which an activity starts. End time : The time at which an activity ends.

    : The time at which an activity ends. Duration : The amount of time that an activity lasts.

    : The amount of time that an activity lasts. Process : A set of activities that is intended to achieve a specific goal or objectives.

    : A set of activities that is intended to achieve a specific goal or objectives. System : All the elements and components of an industrial automation system, including activities, start times, end times, durations, and process definitions.
